IMPROVEMENT `IN' MEAS FOR CMMUNICTING- MOTION TO MACHINERY.

The Schedule referred to in these Letters Patent and making part of the samer ,I, CHARLES H. MILLER, of the city of Buffalo, in the county of Erie and State cf New York, have invented certain Improvements in Means for Communieating Motion to Machinery, of which the following is ai specification.

My improvements relate to certain means to be Aused as a substitute for the ordinary means, such as belting, wire ropes, or shafting, which are employed in communicating motion to machinery where the motive-power is situated Vat a considerable distance therefrom.

justed with great precision tol avoid grcat'wear and i friction; which is always considerable, howevercarefully the bearings are adjusted; Y

Wire-rope, ofthe three means, is, perhaps, the least objectionable for communicating motion when the distance is considerable, although itis quite expensive.

i My invention consists:

First, in the combination of two rock-levers with 'tie-connections of wood or metal, uniting the respective ends of each, together with asuitabl'e number of rocklevers interveningfthe two end ones to support the tie or connecting-pieces, so that the motion which is imparted to the rstdever will be communicated to the last or most remote by the two connecting-pieces,

one of which, during each movement of the recipro.

cation, is subjected-.to acompressive strain, and the other to a tensile strain, whereby the one under ten-1- sion prevents the flexion of the one under `compression, and thereby enables comparatively slender connections of cheap material to bev used, which could not, 'were only a single connection employed.

Secondly, of a slotted armiattached to the first rocking lever, and forming therewith a double bellcrank, which`` connects with the wrist-pin of the rotary power, in combination with a weight supported at the end of an arm projecting fromV .the opposite side of said rocking 1ever,-aud operating as a counter poise for the slotted arm during the movement thereof.

In the accompanying drawing- Figure I isan elevation; n Figure I'I, a cross-verticalsection; and Figure III, a detached fragmentary view. Like letters vdesignate like parts in each of the figures. c

"A-represent-s a water-wheel or motive-power;

B, the crank, and

l), 'the wrist-pin thereof.

O is a rocking lever, and

D, the slotted arm attached thereto and connecting with the wrist-pin l1, which plays in the slot thereof. rllie lever C is pivoted at its center in any suitable bearings, F, represented in the drawing as consisting of two inclined standards.

Cl is a rocking lever, similar to the first one, C, and is supported in similar bearings at the point where the ymachinery to be operated is located.

`The respective ends of these levers O Cl are united by means of strips of wood, H, or other suitable material possessingy the requisite tensile strength to drive the machinery which connects with the end oi' one .of them, as shown at e, iig. I.

The length of these connections H H, which are spliced ati-intervals; as required, will depend on the distance ofthe machinery from the motive-power.

Intermediate of thelevers C G1, other and similar levers, C C2, may be arranged at suitable intervals, to support and steady the connections H, to which they are united by a jointed connection, as shown.

The pivots of the levers and their hearings in the framel or standards F and connections with the ties H, may be of any approved construction, such, for instance, as scale-bearings are provided with, to reduce the friction thereof as much as possible.

I represents the weight suspended .from the end of an arm, J, project-ing from the center of the first lever O on ,the side opposite the slotted arm D', so as to form a counter-poise therefor, so that its weight may not serve to retard the movement of the wheel A or other motive power.

The operation of my improvement is as follows: The wheel A, being set in motion, a rocking movement, through the medium of the slotted arm D, is

imparted Ato the rst lever O, which, through the connections H, communicates a corresponding movcment to the last lever OI at the` 'opposite end.

One ofthe connections H, operating by ltension, and the other by compression, in thus communicating this motion, the flexion of the connection under compression is prevented by the opposite one, which is under tension, and rice versa. Stitfness isnot, therefore, an essential quality in these connections, which may be of any size that possesses the requisite tensile strength.

It is evident that my improvement is adapted to communicate motion in either a horizontal, inclined,

or vertical direction, the supports or bearings for thelevers being arranged to correspond therewith.

When the direction of communication is vertical it is evident that the counterpoise I is not required.

- a wheel or crank-shaft.

My improved device is simple,` may be made of wood, and consequently ceets a great sai-ving over the other methods hereinbefore enumerated; it involves but little friction, and is specially adapted for communicating motion, where the means ure exposed to the action of the weather.

What I claim as my invention is- 1. The combination of the rocking levers C G, tie connections H H, and bearings-or supports F, for communicating motion', substantially as hereinbefore set forth.'

2. The slotted arm Dand eounterpose I, combined and arranged with the rocking levers G C. and connections H H, as hereinbefore set forth.
